#2601: Add four more parameters for carpet

#2601: Add four more parameters for carpet Reporter: Liwei Ji Status: new Milestone: Version: development version Type: enhancement Priority: major Component: Carpet Comment (by Liwei Ji): Hi Roland, thanks. I will add the above test par to `Carpet/test`. We are thinking about add support of mesh refinement to SphericalNR at some point. But not relatively soon. When that happens, we will update this part to make it also works with mesh refinement. Thanks for pointing it out. ‌ In order to get the size of boundary points, I have tried with the par `granularity_boundary`. It is always `0`, even thought in the test par, we have set `CoordBase::boundary_size_x_lower = $boundary_size`. Should we set `granularity_boundary` explicitly in the par file or use `ghost_width[i]` instead for the moment? -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2601/add-four-more-par…

#2601: Add four more parameters for carpet Reporter: Liwei Ji Status: new Milestone: Version: development version Type: enhancement Priority: major Component: Carpet Comment (by Roland Haas): Thank you. I think with those things should be good to go. With the addition of adding this parfile as a test case to Carpet. Shiftout is ok since without the shiftout the first boundary point is exactly on the boundary $eg at -1.0$ and there are not `boundary_size` points _outside_ of the nominal domain $but `boundary_size - 1`$. This is actually intentional since it helps with convergence to have the boundary point stay fixed. Weren’t there plans at one point for SphericalNR to support / use mesh refinement on top of the spherical coordinates? In that case one would have to update this code it would seem. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2601/add-four-more-par…
